L=Standby, H=Normal Operation
Logic Voltage Supply
L=FULL, H=HALF
The Translator is triggered by positive edge of STEP
Pulse.
L=FORWARD, H=REVERSE
L=The Translator is initialized, H=Normal Operation
L=ACTIVE, H=Normal Operation
When the Translator is in initial status, L level is to output.
When the internal protection operation is detected, L level
is to output.
Logic Ground
